神经再生一直是多年来人们研究的课题之一

神经细胞是高度分化的细胞

一般认为在发育完全的神经系统内不形成新的神经细胞

它的数目在胚胎发生期中就已经决定。近年来我国学者发现在损伤和其他条件下脑和脊神经节、植物性神经节中的神经细胞可进行有丝分裂或无丝分裂

但是关于We studied effect of acupuncture on regeneration of rat's hypoglossal herve.A total of 41 adult albino rats were used

among those 21 cases were of acupunctured and 20 cases were of controls.After the right hypoglossal nerves were severed

rats were reared for 7

10

or 14 days.In this period

we gave acupuncture therapy to the acupunctured but nothing to the controls.The regeneration was examined by the retrograde transport method of HRP.The results were as follows:7 days after the nerves were severed

regenerations were not found in the nerves of two groups.10 days after the nerves were severed

regenerations can be found in the nerves of the 90% of the acupu- netured but only 44% of the controls.It is significant statistically(P=0.05). 14 days after the nerves were severed

regenerations can be found in the ne- rves of two groups and more regenerated nerve fibers in the acupunctured as compared with the controls.It was found that regenerations of the hypoglo- ssal nerves of the acupunctured were quicker than those of the controls.It was shown that acupuncture promoted the regeneration of rat's hypoglossal nerve.
